Norm, what do you get from ifconfig? are you positive that the network 
services aren't turned on?

Just a stab in the dark, try to disable Ipv6
"To disable IPV6: As root, you must add the line: "alias net-pf-10 off" 
(without quotes)
to the end of your /etc/modprobe.conf file.
-OR-
Quick solution:
[root at charon fc3]# echo "alias net-pf-10 off" >> /etc/modprobe.conf
A reboot is required.
"

alternate way
"Create a file in /etc/modprobe.d called blacklist-ipv6
The file should contain:
# Disable IPv6
blacklist ipv6
Reboot, and IPv6 will no longer be enabled on the system. You can 
confirm with:
/sbin/ifconfig -a
"
